## Specifications (measured at TA 25°C, full load after warm-up) 

## Application Note: 

## 1. Recommended external input fuse 1A/slow blow type. 

2. To measure the output ripple & noise short runs by 0.1uF/50V&47uF/50V @20MHz, nominal input and full load. Please see as above. 

3. That Pin 7 is NC but need 4mm minimum clearance to ground for safety.
